Patented Dec. 1, 1931 UNITED "STATES newline, or COLUMBUS, OHIO VALVE PROTECTOR Application filed September '3, 1929. Serial no; 390,104)

. My invention relates to a valve protector and particularly to a device for protecting the valves of containers of gasesunder pressure.

The object of my invention is to provide a 5 valve protector that may quickly and easily be detached'from the gas container,

but which will be securely held in place dur-.

ing transportation and rough handling ofthe gas container. I 1

Another object of my device is to provide a device that will prevent the loss ofthe protector or cap, which the consumer now often fails to return to the owners of the gas containers or cylindersbecause of the frequent being removed, due to some damage that has been done the threads on the cap flange by careless handling. 7

Another object of the invention is to pro- "20'tect the threads now common on standard caps by surroundlng them with a protectmg ledge or flange that will prevent the threads from coming in contact with objects that heretoforehavemutilated the threads;

Another object is to provide a cap in two separable parts, one of which may remain permanently screwed on to the standard cap flange, whilethe other part may be'quickly removed from over the valve.

30 lVith these and other objects in view, which will be apparent as the description proceeds,

I will now describe my invention in connection with the accompanying drawings, in which Fig. 1 is a plan view of one part of my .valvc protector;

Fig. 2 is a view partly in section on the line 2-2 of Fig. 1; I

Fig. 3 is an elevation of the same part shown in Figs. 1 and 2;

Fig. 1 is a. top plan view of another part of my device; v v

Fig. 5 is a sectional view on the line 55 V of Fig. 4;

Fig. 6 is a section on the line 6-6 of Fig. 1; Fig. 7 is a sectional view of my device as applied to a standard gas container;

Fig. 8 is a sectional view of a modification of my device.

1 is a flange proj ecting from a screw threaded -cylindricalpart 2. the 'other side of the flange 1 from the screw threaded portion2 thereis a cylindrical portion 3having widelugs 4-4.

O fthe'partsshown in Figs.;{1, 5. and 9 is an internal screw thread adapted to receive the. standard flange cap 6' of Fig. 7. This screw thread 9 is made in an upwardly extending portion 10 which iszsurrounded by a groove 11 having widened portions 12'and' overhanging flanges 13.13. The cap flange 516 is of standardconstruction and is fitted securely to the gas container .17 so as to se.

. curely hold the'cap flangeon to the container. ls'difiiculty found in replacing the caps after 20 is thestandard plug or valve screwedcinto "65 the neck of the container and which should otherwise injured or accidentally turned dur ing transportation or handling of the container. 1

f Theparts of my deviceshown in Figsi l,

5 and 6' may be screwed on to the. cap flange f 16 and unscrewed therefromor it may remain permanently attachedthereto. The cap. pore tion 21 is screw threadedasshown in Fig. 7

at its bottom portion and may be screwed 'on to the portion 2 of the parts shown in Figs. 1, 2 and 3. I mayhold these par-ts ;to-

gether and keep one from unscrewing from the other by pins 22. After the parts shown in Figs. '4, 5 and 6 are'screwed on to theicap flange 16 theparts shown in Figs. 1, 2 and'3 'may be attachedquickly and easily by inserti'ngthe part 1in the widened portion 12 'ofthe groove 11 and giving it a quarter turn,

thus bringing the portion 4 under the, widenedportion 13 where it will be held untilgiven another quarter turn.

The cap 21 including the parts shown Figs. 1, 2 and 3 when fastened together as shown in Fig. 7 may be easily attached to the parts shown in Figs. 4, 5 and 6 by placing the cap over'the valve 20 and bringingthepor tion 4 into the groove 12 and then giving thecap" a quarter turn. To remove the cap 21 cap, flange 16.-This will protect'the cap :i

flange 16 from mutilation by a part that will resist the ordinary rough handling of these parts, and it will be observed that none of the parts of my device will be mutilated by rough handling, and the caps will not be'los-t' because I I the users cannot replace them by reason'of the mutilation of some of the attached por-' tions. .Moreover, it will be observed that my cap 21'may be easily attached andmoved from the gas container by quarter turn oi;

the cap.

In Fig. 8

I haveshown a modification. of.

wardly extended external screw threaded portion screwed into the lower end of the cap portion, said third intermediate portion having an outwardly extending flange to fit over the top of said first portion and a downwardly extending portion to extend into the groove in said first portion, there being a bayonet join-t construction between said first and third portions.
